A British Medical Association conference has considered the possibility of imposing a new "fat tax" on cakes, cookies and certain processed foods to help combat the growing problem of obesity.

The current rules surrounding Britain's 17.5 percent value added tax (VAT) on food are complicated. Most foods are exempt from the VAT, but shoppers currently pay the VAT on ice cream and marshmallows (which are considered luxuries) not on baked Alaska or marshmallow teacakes.

Dr Martin Breach, who proposed extending the tax, said obesity causes heart disease, diabetes, circulation problems, high blood pressure and joint problems.

He contended that extending the tax would raise a significant amount for the British treasury, helping cover the cost of treating obesity, heart disease and diabetes.
